Thanks for keeping it civil....as always it good talking with ya!!
I guess we really should ask how he plans to use the car. If he has no future plans for the track, auto-x, or care about the cool factor of a c/o based suspension then I would save the money and go with leafs....plus it speeds along the build time a little and they work.
For the record, if I was to do my car again I'm sure I would do the LG 3-link....but I did my suspension years ago and I have no interest in starting over at this point ....
